I've watched Django and it got me wondering how slaves were actually treated. I've heard a lot of Lost Cause crap on how slaves were happy, having decent healthcare with rapes and beatings being illegal (no joke I've actually came across a redditor that believed that).

So how brutal were slaves treated during the 1860s? How common/uncommon were beatings and rapes of slaves? I've heard that outright killing slaves was rare, but beating them to 1 inch of life left was pretty common. Did slaves really get some sort of medical treatment from their masters because slaves were just that expensive? I know it might require a lot of writing, but I'm okay if you can answer one of the questions. Thanks in advance!
